Principal Investigator

a) Long-term outcomes following acute pulmonary embolism

  • Responsible for establishing one of the largest confirmed pulmonary embolism cohort database in Australia. This is an ongoing project to assess the long-term outcomes of patients in a contemporary setting.

b) A contemporary population study on thromboembolism and its short and long-term impact on morbidity and mortality

  • This is a population-level study exploring the epidemiology and cohort's health and outcomes following thromboembolic events
